Hunter offers a new communications solution for IMMS central control: an Ethernet, or Local Area Network (LAN) Com module. The ACC-COM-LAN looks like other ACC communications modules from the front, but features a standard network jack on the back for easy connection to a customer’s computer network.
Many IMMS customers and prospects already have an existing communications channel at their fingertips. Computers, printers, and other devices already communicate with one another over what is often simply called the “network”.
In most cases, the “network” is actually an Ethernet system designed to move data around buildings, facilities, and even entire cities over special cabling. With Hunter’s new option, this technology can now be used for IMMS communications, and offers many advantages over more traditional communications.
Ethernet is fast, reliable, and secure. It is maintained by the customer’s Information Technology department, and there is no monthly charge or licensing fees. The communications infrastructure is already in place in many institutional and governmental installations, and using it is often just a matter of asking permission.
ACC-COM-LAN looks just like the other ACC communications modules from the front. The reverse side has a standard network jack, or 8P8C (8-pin, 8-conductor). This is sometimes called an “RJ-45” jack, which are commonly found on the port panels of most computers.
Ethernet works on IP (internet protocol) addresses, and the ACC-COM-LAN uses a “fixed IP” assigned by the network administrator. The com module is also assigned a standard IMMS address for use by the central software, in the usual manner at the com module. The LAN or Ethernet module can still also be used to reach additional controllers via UHF radio or hardwired cable. Controllers on the site can share the IP connection by adding ACC-COM-HWR to the other controllers, with appropriate radio or hardwire options (RADxxx or ACC-HWIM).
The controller with the ACC-COM-LAN installed can be up to 100 m (300 ft) from the Ethernet jack. Wiring is done with CAT5, CAT5e, or CAT6 cable, and is determined by network requirements. Customers who desire remote access to their IMMS control system may do so via remote desktop software if the administrators permit this. Most Ethernet systems allow direct outside access via the Internet, with appropriate security settings.
This exciting new option is available now, and is expected to make an industry-wide impact on large-scale systems around the world.
